How long has this been going on? Since you had the unit installed? It is a sign of inadequate water volume of the boiler in the system, requiring the addition of a water-line extender tank. An auitomatic water feeder isn't an adequate fix for the problem, in fact, they're more a nuisance than a useful device for a residential system.
